Study of the speeds of vehicles involved in collisions through analysis of mechanical deformations of structural parts

This work consists of describing a method for calculating the speed of vehicles involved in traffic accidents through the analysis of mechanical deformations in various parts of these vehicles. The method is not new in the world, but in Brazil studies are at an embryonic stage, with some methods being applied such as conservation of total energy and conservation of momentum, but in both cases the deformations of the parts are not taken into account. , although a considerable part of the energy or momentum is used to cause the deformation itself. Some authors describe in their scientific works each of these methods for calculating speed, but they do not take into account, for example, the moment of inertia of each vehicle, when they consider it as an estimate to be added when calculating the speed of each vehicle. one of the vehicles the damage observed in the vehicles, but fails to take into account the mechanical deformations occurring in their structures. The objective of this is the analysis of deformations in structural parts of motor vehicles involved in traffic accidents and a possible way to determine or estimate the traffic speed of each vehicle before the collision. This study applies knowledge about mechanical deformations in the practice of calculating collision speeds in traffic accidents, in the field of forensic engineering, and with this, seeks to point out, in many cases, the true cause of the speeding violation, or a more approximate calculation of the true value of the speeds of the vehicles involved in a collision.
